a simple class to control print indentation
Definition: vtkIndent.h:34
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
Superclass for algorithms that produce only polydata as output.
extracts points whose scalar value satisfies threshold criterion
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void ThresholdByLower(double lower)
Criterion is cells whose scalars are less or equal to lower threshold.
~vtkThresholdPoints() override=default
static vtkThresholdPoints * New()
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
void ThresholdBetween(double lower, double upper)
Criterion is cells whose scalars are between lower and upper thresholds (inclusive of the end values)...
void ThresholdByUpper(double upper)
Criterion is cells whose scalars are greater or equal to upper threshold.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
